I just installed Fedora 15 on my Dell E5420. I am having trouble with it detecting the touchpad as a touchpad. Initially the Touchpad part of System Settings>Input Devices was greyed out and now it does not exist at all. I have tried a few of the fixes I have found on other sites (mainly running the ALPS pad with Synaptics drivers) and nothing seems to work. The goal for me is to enable scrolling and to get rid of tap to click.

What I have done so far is:

1. Create a xorg.conf file using Xorg :1 -configure then moving it to the etc/X11 dir using cp xorg.conf.new /etc/X11/xorg.conf
